Abstract: TITLE            BIDIRECTIONAL AXIALLY PLIANT PRESSURE       ASSISTED SEAT FOR A VALVE                         ABSTRACT     A valve seat especially adapted for a high performance butterfly valve is characterized by flexing axially rather than stretching radially when the seat interfaces with a closure member.  In the preferred form, a seat has a support member embedded therein to provide restorative forces which tend to urge the valve seat to a predetermined position in response to axial flexing.

Abstract: ROLLER SLIDE OR SLIDE     ABSTRACT OF THE DISCLOSURE     Intermediate regions are provided between straight and circular-arc slide sections having a curved sliding surface in cross-section, said intermediate regions being clothoid-shaped in top view. In said intermediate region, which starts will a quarter-elliptic cross-sec-tion of the sliding surface at the outer side of the curve corresponding to the cross-sectional shape of the straight slide section, the ratio between the major and the minor axis of the ellipse continuously changes towards the other end so that the individual trajectories depending on the velocity of the vehicle form in top view a sheaf of clo-thoids having the same initial point. The individual structural elements of the slide are flanged at their ends, one flange, each, of two structural elements being adju-stable in various directions and supported by a strut.

Abstract: ABSTRACT OF THE DISCLOSURE     A continuous closed-loop process for directly producing potassium chlorate by electrolysis of an aqueous potassium chloride solution with a metal anode is described.  The process provides surprising advantages in efficiency by comparison with conventional double decomposition processes for producing potassium chlorate from electrolyzed sodium chloride.  The metal anode is coated with a precious metal, oxide or alloy or a platinate.  The aqueous solution is passed through a heat exchanger using a heated cooling medium which is at a temperatue below the equilibrium temperature of the solution in the cell but above the temperature atwhich potassium chlorate crystallizes from solutions of the concentration selected for the process.  In effluent solution containing potassium chlorate is removed from the cell and cooled until crystals of the chlorate form.  The crystals are removed from effluent and the latter is  enriched by adding a controlled amount of potassium chloride thereto.  The enriched effluent is returned and added to the electrolytic cell for further electrolysis, at a volume rate equal to the rate at which the unenriched effluent is removed from the cell.

Abstract: LINE POWERED TRANSFORMERLESS    LOUDSPEAKIMG TELEPHONE          Abstract of the Disclosure A line powered loudspeaking telephone is implemented entirely from electronic components, eliminating inductors and transformers.  A three stage output amplifier is used with the loudspeaker impedance forming the output stage impedance.  A feedback network is used between the amplifier input and output stages to provide the desired gain at audio frequencies while forcing the DC gain to unity.  The circuit then functions to provide proper gain for audio frequency signals received from the communication line while reflecting onto the communication line the resistive component of the output stage impedance scaled by biasing circuit elements of the amplifier input stage, thereby maintaining the proper voltage-current characteristic of the communication line.

Abstract: METHOD AND APPARATUS FOR MONITORING VASCULAR FLOW     ABSTRACT         A method and device for measuring blood Plow through a blood vessel within human or animal bodies.  It utilizes the principle of energy conversion to heat by myocardial activity, organ metabolism, and laminar frictional flow in blood vessels and measures the heat dissipation through the vessel wall with obstruction to flow.  When the device of the invention is placed next to the vessel wall, the output signal correlates blood flow with temperature.  With an obstruction to flow, the temperature drops.  The device is placed in series proximal and distal to the repaired vessel to be studied.  The leads are brought through the skin and attached to a temperature monitor.

Abstract: ABSTRACT     A pushbutton control system for raising and lowering the dump body of a dump vehicle.  Included are "up", "hold" and "down/-float" switches which are connected in circuit with "up". "down" and "float" solenoid valves.  These valves on energization direct pressurized air into the "up", "down" and "float" chambers of two air cylinders included in an actuating mechanism for a hoist valve controlling the telescopic hoist cylinders of the vehicle.  The dump body is raised upon depression of the "up" switch with the consequent opening of the "up" valve.  The depression of the "down/float" switch, resulting in the opening of the "down" valve, causes the dump body to lower by the forced contraction of the hoist cylinders.  Upon subsequent release of the "down/float" switch the "float" valve opens to allow the dump body to lower un-der its own weight.  The depression of the "hold" switch, with the consequent closure of all the solenoid valves, makes it possible to hold the dump body against movement in any desired position.  Pilot lamps are provided to indicate the operating conditions of the con-trol system in response to the actuation of the switches.
